Vascular plants first appeared during the Silurian period, and by the Devonian had diversified and spread into many different land environments. They have a number of adaptations that allowed them to overcome the limitations of the bryophytes.

xylem In vascular plants, the tissue that conducts water and minerals; xylem consists, in various plants, of tracheids, vessel members, fibers, and parenchyma.

Cryptogams: nonvascular plants such as lichens and mosses that make up the ground or surface layer of vegetation.

The more primitive plants are dependent on living in water either totally or partially and the more advanced vascular plants have found ways to live independently on land.

Vascular plants can be divided into seedless (ex. ferns) and seeded. Vascular seeded plants can be divided into gymnosperms (ex. pines) and flowering plants (angiosperms). Angiosperms can be divided into monocots and dicots.

If you look at a single acre of prairie, you'll find about 200 species of flowering and other vascular plants in it. If you look in the soil, you'll find at least 5,000 different species of bacteria, probably a thousand or so species of fungi.

The order of the genes between the arrows (~6:30 to ~10:00) is also found in the lycopsids. But in all other vascular plants, this region is inverted and the order of the genes is precisely reversed.

leaf -- An organ found in most vascular plants; it consists of a flat lamina (blade) and a petiole (stalk). Many flowering plants have additionally a pair of small stipules near the base of the petiole.
